Second photo is the best one for determining if you have everything centered up & it looks right! I don't know anything about that particular board!
Is it a "Directional Twin?" If it is then the 1 inch set back is probably right! If it isn't? Center the bindings nose to tail! (even if that puts your stance wider or narrower than you'd prefer! With a True Twin board, centered front to back is more important than ideal stance width!

Then, just be sure all your binding mounting screws are good & tight! If they are,..? Go ride! Don't like the way it feels? Adjust bindings accordingly!
